ALFRED w. CHAPMAN, or CLEVELAND, onr lAssrsnon TO THE DQNLEY BROTHERS iCOMPANY, OF CLEVELAND, onro, A ooRPoR 'rIoN- 1 WINDOW-FRAME FILLER ANDGUIDE.

Application filed August 21, 1926; Serial No. 130,678.

This invention relates to window frames of steel, or' other metal, setin masonry building construction, and appertains more particularly tomeans for effecting tight joints between such metal frames andbrickwork.

In the setting of steel window frames in n'iasonry, and especially inwalls of brick, as such frames are usually fashioned, it has been founddifficult, and an unstable practice, to fill and point with mortar thevertically disposed chinks left open between the bricks and the outerside rails of the frames. And a further inconvenience arises from theabsence in steel window frames of any sort of guide for the bricks toabut against in laying up the outer face of the wall adjoining theframe. These structural. deficiencies lead to error, bad workmanship andvexatious impediments in the setting of such frames, and are likely toresult in imperfect outer joints at the sides of the frames, which sooncrumble on exposure to bad weather and the jarring of traffic.

. Thus the prime object of the present invention is to provide efhcientand practical means for overcoming the aforesaid incongruities, andwhich will facilitate the setting of metal window frames in masonrywalls in a workmanlike and durable manner. Another important object isto produce an inexpensive attachment that can be quickly and easilyapplied to the frames, adjusted for position, and readily detached forfitting to peculiarities of the setting. A further purpose is to furnisha filler and guide strip that may be sprung on to the side rails of asash frame, but held rigidly in position when the frame is set in awall.

Although the device is intended for use in any metal window or doorframe to which it may be adapted. it is found especially advantageous inthe construction of windows in basement walls of brick, such as shown inthe accompanying drawing which I proceed to describe.

Fig. 1 of the drawing is an outside elevation of a steel and glazedwindow set in a masonry basement wall.

Fig. V2 is an enlarged and foreshortened vertical section taken on line22 of Fig. 1.

Fig. 3 is a detailed horizontal section taken on line 33 of Fig. 2.

Fig. 4 is an end view of the filler and guide strip, and

1 Fig. 5 is a side View of the same.

"The reference numeral 1 indicates a brick wall having a window aperturetherein, the sides of which are shown at 2. To provide a lintel itiscustomary to span the window opening with a palr of angleirons 3 and 3for supporting the overlaid brickwork 2., and these angles receive andhold between them the upper projecting vertical wing of the top Trail4.- of the window frame; which frame is a rectangle of .T-bar with thestem of the T section projecting inwardly, its side rails being shown at4: in Figs. 1 and 3, and its bottom rail at 4! in Figs. 1 and 2. Thespaces. all around the frame 4 are filled with cement mortar, as shown,and it rests on the sill bricks 2 with a filling of mortar underneath.

The sash5 is usually formed of T-baralso, a smaller size than the framebeing used, and it maybe hinged to the frame'rail 4 as at 6, Fig. 2. Thesash is provided with glass panes 7 held in place by suitable clips andputty.

Now in this standard steel window and masonry construction it will benoticed that, in order to lay the bricks flush at the outer face ofthewall l, elongated vertical chinks, somewhat wider than the thicknessof the upright wing of the angle iron 3, are left on each side of thewindow opening between the side rails 4 of the frame and the brick sides2. These chinks extend the full height of the window aperture, arebothersome to fill and point with mortar, and such filling underordinary conditionssoon crumbles and falls out. To remedy this defect Iprovide a filler strip 8 of sheet metal bent in a U-shape lengthwise,which forms a deep groove therein titted to be sprung over the outerwing of the side rail at of the frame, and held thereon by friction. Theoutside margin of the strip 8 is bent to form a flange 9 projecting atright angles to its body part as best shown in Figs. 4 and 5.

Thus the flange 9 of the filler strip forms a guide for the bricks toabut against in laying up the wall 2, for the flange should be wideenough to overlap the wall somewhat. The said flange also covers thechink between the frame rail 4' and the bricks 2, so that cement mortar10, Fig. 3, can be compacted in said chink against the strip 8 and itsflange to form a durable and invisible joint.

1.r An attachment for a metal Window frame comprising a sheet metalstrip having a deep longitudinal groove formed therein to receive and tofrictionally engage a side rail of said frame, and a flange PIOJQCtHIgoutwardly at right angles to the body portion of said strip.

2. In a metal Window frame, a side rail of said frame provided with adetachablesheet metal strip sprung thereon so as to frletlonally embracesaid rail, and a flanged margin of said strip projecting outwardly atright angles to the frame.

3. In a metal Window frame, a side rail' of said frame, a sheetmetalstrip having a deep longitudinal groove formed therein adapting it to besprung on and to frictionally embrace said side rail, and a flangedmargin of said strip extended outwardly at right anglesto said siderail.
